Hello, everyone
Can you help me with the following:
I have a matrix (3x3, for example) and a vector (i.e. 3x1 matrix), I
want to multiply them, and the resulting vector I want to draw on
screen.
In other words, I need function to multiply two matrixes, function to
get calculate determinant and rank of matrix, and function to draw 3d
line. Is it possible to do this in python?
